Itâs not a surprise that people still want to buy lottery tickets even in difficult financial times. For usually a small entry fee, people get the chance to win huge prizes that can give people the opportunity to do things they have always dreamed of.
REM sleep typically occupies 20â25% of total sleep in adult humans: about 90â120 minutes of a night's sleep. The first REM episode occurs about 70 minutes after falling asleep. Cycles of about 90 minutes each follow, with each cycle including a larger proportion of REM sleep.
The sleep cycle repeats 4-6 times a night. We don't necessarily always progress through the sleep stages in a linear fashion. If your sleep is normal, you may reach your first REMcycle 60 to 90 minutes after you fall asleep, having gone from stage 1 to 2 to Delta to REM. This Delta may last 10 to 15 minutes and this REM may be very short.
